中文摘要:
      彰武水库是河南省境内海河流域的主要水库,由于自然和人为因素影响,库内水体水质较差。为了强化水库水环境安全工作、确保水库水质,以该水库作为研究对象,通过DPSIR模型建立了该水库水环境安全评估指标体系,根据熵值法计算了各指标的权重,尝试用云模型对其2015年的水环境安全状况予以评估。结果表明:该水库水环境为较安全级别,但存在安全隐患;由于周边较多废弃的工矿企业,其工业废水和农业化肥农药,随降雨和灌溉退水而排入水库,再加上传统的网箱养殖方式,使其TN、TP的浓度严重超标,水库水质全年为劣V类,需引起水库管理部门的重视。云模型能减少评估过程中的不确定性,其评估结果与实际相符,可用于水体环境的安全评估。
英文摘要:
      As a main reservoir of Haihe River Basin in Henan Province, the water quality of Zhangwu Reservoir is poor in recent years due to natural and human factors. To strengthen the reservoirs' water environmental safety and to ensure the water quality, the Zhangwu Reservoir was taken as research object, the indexes system of its' water environmental safety were stablished using the DPSIR model, the weight of each index was determined by the entropy value method and the rank of water environmental safety in 2015 was evaluated with cloud model. The results showed that the rank of water environment of the reservoir was relative safe, but there were potential safety hazards. There were many abandoned industrial and mining enterprises around the reservoir, and the industrial waste water and agricultural chemical fertilizer and pesticides were discharged into the reservoir with rainfall and irrigation withdrawal water, coupled with the traditional cage farming mode, which made the concentration of TN and TP severely exceed the standard, and the water quality of the reservoir was V kind throughout the year, which the reservoir management department needs to pay more attention. We conclude that the cloud model can reduce the uncertainty during evaluation process and its evaluation results were consistent with the reality, which can be used to evaluate water environmental safety.
